Product Description

The Celestron 70mm Travel Scope is a very inexpensive little refractor of many uses: a great scope to start the kids on astronomy; your own spur-of-the-moment backyard scope for astronomy, birding, and nature studies; a scope to sit on the porch of the home with a view to while away the lazy summer afternoons and evenings; a toss-in-the-trunk-of-the-car take-along for vacations and day trips; and more. Its tripod can serve double duty as a nifty light-weight photo tripod for your camera.

You get an lot of features and performance for not a lot of money with the compact Celestron 70mm Travel Scope: fully-coated achromatic optics, two 1.25" eyepieces, finderscope, erect image diagonal, adjustable height tripod/altazimuth mount, backpack carrying/storage case, and TheSky X- First Light Edition planetarium/star charting software on CD-ROM. And it weighs only 3.3 pounds, so it's easy to take with you anywhere you go.

The erect image diagonal gives you eyepiece views that are oriented the same as they are to your bare eye. This lets you easily follow moving wildlife and vehicles without the annoying image reversal you find with a conventional diagonal. Plus, printing (the name and home port on a distant boat, for example) is completely readable, instead of being backwards. Close focus is only 19', letting you get up close and personal with the nature in your own back yard.
While not a powerhouse of an astronomical scope, the Celestron Travel Scope 70 might surprise you with its capabilities outside our atmosphere.

You will find a lot of uses for the respectable optics of the Celestron 70mm Travel Scope, and a lot of times and places to use them, day or night. For the price, it's hard to beat this nifty little refractor.

This Telescope's Optical System . . .

Achromatic refractor: 70mm aperture, 400mm focal length, f/5.7. All-glass crown and flint doublet refractor with built-in lens shade to improve contrast. Fully antireflection coated on all air-to-glass surfaces for good light transmission and contrast.

Finderscope: 5 x 24mm straight-through refractor.

Focuser: 1.25" rack and pinion.

Star diagonal: 1.25" 45° erect image/right reading prism type.

Two 1.25" eyepieces: The first is a 20mm providing 20x. The eyepiece field of view is 2.5° across, five times the diameter of the full Moon for expansive views of the Moon, the brighter large-scale deep space objects like open star clusters and nebulas, and terrestrial observing. The second is a 10mm providing 40x with a 1.3° field for more close-up views of the Moon, nature, and more. Optional 1.25" eyepiece can expand the magnification range.

This Telescope's Mount . . .

Altazimuth mount: The Travel Scope 70 comes with a preassembled adjustable height photo tripod that serves as an altazimuth mount for astronomical and terrestrial observing. A no-tool mounting foot on the optical tube connects the 17" long scope to the tripod by means of a single hand-tighten 1/4"-20 thread bolt for fast set-up and take-down. The four-section legs and rising center post let you adjust the tripod height from about 16" to 49". A lock knob adjusts the friction and smoothness of travel in azimuth (side to side) while the twist-to-lock pan handle does the same for motion in altitude (up and down). The pan handle lets you manually aim the scope and track moving objects with precision.

Carry case: The scope comes with a soft backpack-type carrying/storage case that holds scope, tripod, and eyepieces, inviting you to toss the Travel Scope 70 in the trunk of your car to take it with you wherever and whenever you go.

Two-year warranty: All Celestron telescopes have a two-year warranty, double that of competitive scopes.

Great little scope, good for quick setup and views of the Moon or Jupiter, useful for wide-field shots, and well built enough to function as an introductory wide-field DSLR lens. Chromatic aberration is mild (less than some vintage telephoto lenses in the same focal range), and the smaller aperture makes it easy to add a solar filter inside the front cap. I took the lenses out and painted the edges black, which resulted in a very slight increase in contrast.

That said, the tripod is junk. Unadulterated, unmitigated junk. Pitch it and grab pretty much any thrift-store medium-height photography tripod and you'll be much better off. The backpack is useful for keeping stuff together with the scope, not so much for actually hauling the scope around. But again, pitch the tripod, it's not worth even messing with.

I purchased one of these as a starting point. The tripod can be frustrating so be patient. I feel it's a usable little no frills scope. I eventually upgraded to a nexstar slt mak / cass and sometimes use this on the tracking mount for wider views. (Posted on 7/22/2019)

This little fella is maybe good for a lark. I took mine camping and was able to find some of the brighter nebulae. But the tripod is shaky and the views are muddled. The supplied eyepiece will need an upgrade.

I would say get a small Nexstar like a 4 or 5. The goto ability would be better for a beginner. Also, the smaller Nexstar units come with a little better actual telescope.

If this unit is all you can afford for a telescope, you probably will not be that happy with it after the novelty wears off. (Posted on 1/2/2019)

Got this when I thought i wanted to take up astronomy as a hobby. Excellent choice for that! It’s very affordable and I can see more than I thought I could with it!

That said, you get what you pay for. I have a much sturdier tripod I use with my camera and switched to it after trying the included tripod once. A really good tripod costs much more than this whole kit does, so as a backup for when I’m using my good tripod, I got an Amazon Basics tripod. Low cost and much sturdier than this one. This will get you started, but get a better tripod if you decide to continue.

Also, the backpack case is nice, but it’s not padded and provides no protection to the scope. I wrap the pack in a blanket to carry in my truck. So far, that’s been enough.

I recommend this scope if you’re thinking of starting astronomy as a hobby like I was. It’s enough to see if you like it, and cheap enough to give to someone else if you don’t. (Keep the original tripod for if you give it away!).

I’ve got a bigger, better, (much) more expensive scope now, but still have this one in my truck and use it for viewing things like the Moon and the Pleiades. It’s much better for those than my 6” Newtonian! (Posted on 1/1/2019)

I received this scope as a gift from my daughter; I've modified it a bit, and now it travels with me all the time, and I use it for comet-watching, moon-watching, and even some DSO's when I'm in a dark location. I keep it packed up with a Celestron 8-24mm zoom and a couple of other eyepieces, and that covers a lot of situations. However, I had to replace the supplied tripod with a sturdy lightweight photo tripod, found at a thrift store. The finder was useless, but I replaced it with a red-dot finder; often a finder is not needed anyway for this scope. With the modifications I made, it's a pretty decent travel kit.

This is a great little scope for the price. I have taken it on many camping trips; it's easy to set up & the optics are more than decent for the price. My only complaint is the wobbly mount. But it's more than worthwhile for its light weight & ease of transport, plus if lost or damaged it won't break the bank. We traveled to Idaho for last year's solar eclipse & used this little guy as a projector. I've shown the neighborhood kids (and adults!) close-ups of a lunar eclipse. It has gotten my nephew & niece totally hooked on sky-watching, so much so that they've asked for their own scope this Christmas. I never take a road trip without it! (Posted on 11/30/2018)

I bought this scope for the Aug 2017 eclipse because I was going to be in Alaska but still wanted to view it. It did its job - was small and compact, easy to transport, and was good enough to view the eclipse. The focuser is plastic, but functional. Don't bother with using the supplied finder scope, it is too small to be useful. The kellner eyepieces are useable, but the scope does better with some plossels. The glass main objective lens is actually decent. Some chromatic aberration, but not too much. Like I said, it is great for what it is, a cheap travel size scope. (Posted on 10/24/2018)
